vented certain new and useful Improvements in Window-Fasteners, of which the following is a specification, reference being had therein to the accompanying drawings.

The invention relates to window fasteners and is more particularly designed for use in connection with vehicle windows, the invention comprising the construction as hereinafter set forth.

In the drawings: Figure 1 is a sectional elevation of the fastener showing in full 1 lines the window sash and frame; Fig. 2 is a front elevation partly in section of Fig.1,

and Figs. 3 and 4 are perspective views'of two of the cooperating parts of the fastener.

A is a member for attachment to the window sash, preferably provided with an an gle portion for embracing the top rail of said sash, and having an'upwardly-extending hook B and an outwardly-extending lift.

or handle 0.

D is a tubular casing inserted laterally in,

a recess in the window frame. The bottom of this casing is slotted at E to receive the hook B,and the outer end of the casing has a flange F for attachment to, the window frame. This casing may be conveniently made from a piece of metal tubing, and'the inner end is closed by turned flanges G.

Fitting within the tubular casing D is a slidable block H, which has a shoulder I for engagement with the hook B. The outer end of this block has a reduced portion J which passes through a keeper plate K and forms a push-button for sliding the block. Atthe inner end of the block is a spring L Washin ton, D. c.

and yieldably presses the block outward, as shownin Fig. 1. e

Inoperation,.when the parts are secured a which abuts against the end G of the casing, I

in position the hook B will register with the slot Ein thecasing and a corresponding slot in the rail, so that the raising of the win-' dow sash will move said hook into said slot. The sliding block His also slotted at H andthe shoulder I is formed at one end of said slot." Whenever the sash is raised to close the window the hook B passing into theslot H of the slidable blockI-I will force the latter laterally within the casing D against the tension of the spring L, but as soon as the hook passes the shoulder I the block will I snap outward to effect an engagement of said shoulder with the hook. To disengage the p'artsit isonly necessary to press upon the button J, which will slide the block inward against the tension of the spring L and withdraw thehook from the shoulder I, so

as to permitthe lowering of the sash.

What I claim as my invention is The combination with a window: frame and sash, of a hook carried by the sash, a latch memberengaged by said hook in a certain position of the sash, said latch member being mounted in a the window frame and slidable transverse to the plane of the sash,

a spring. acting on the latch member to ena gage it with said hook, and means for manually displacing the latch member fromengagement with the hook.

In testimony whereof I affix my signature in'the presence of two witnesses. v
